Impact of insufficient doses of medications on Helicobacter pylori eradication: a retrospective observational study.

BACKGROUND AND AIMS: The doses of medications may influence the success of Helicobacter pylori (H. pylori) eradication. This real-world observational study aimed to explore the impact of insufficient doses of medications prescribed for the bismuth-containing quadruple therapy (BQT) regimen on successful H. pylori eradication. METHODS: We retrospectively screened the patients who were diagnosed with H. pylori infection and received BQT regimens for H. pylori eradication at our department between January 2017 and July 2020. The rate of successful H. pylori eradication was compared according to the doses of medications prescribed. Standard doses were defined according to the clinical guidelines. RESULTS: Overall, 1054 patients were included. The rate of successful H. pylori eradication was 78.2% (824/1054). Among them, proton pump inhibitors (PPIs) and antibiotics were prescribed at insufficient doses in 37.0% (390/1054) and 6.7% (71/1054) of patients, respectively. Furthermore, pantoprazole (98.7% [385/390]) was the most common type of PPIs prescribed at insufficient doses, and nitroimidazoles (85.9% [61/71]) were the most common type of antibiotics prescribed at insufficient doses. Among the patients receiving colloidal bismuth pectin (CBP) (200 mg tid) and standard-dose antibiotics, the rate of successful H. pylori eradication was lower in insufficient-dose PPIs group than standard-dose PPIs group (78.1% [271/347] versus 82.6% [438/530], P = 0.095). Among the patients receiving CBP (200 mg tid) and standard-dose PPIs, the rate of successful H. pylori eradication was significantly lower in insufficient-dose antibiotics group than standard-dose antibiotics group (37.8% [14/37] versus 82.6% [438/530], P < 0.0001). Among the patients receiving CBP 200 mg tid, the rate of successful H. pylori eradication was significantly lower in patients receiving both PPIs and antibiotics at insufficient doses than those at standard doses (46.4% [13/28] versus 82.6% [438/530], P < 0.0001). CONCLUSION: Among the BQT regimens, PPIs and/or antibiotics, especially pantoprazole and metronidazole, are often prescribed at insufficient doses, compromising the success of H. pylori eradication.

Low-molecular-weight heparin followed by rivaroxaban for acute occlusive portomesenteric vein thrombosis in a cirrhotic patient treated with multiple endoscopic variceal procedures.

Acute portomesenteric vein thrombosis is potentially lethal. In the present paper, a cirrhotic patient with a previous history of esophageal variceal bleeding presented with acute occlusive portomesenteric vein thrombosis, but achieved complete recanalization by low-molecular-weight heparin followed by rivaroxaban. Notably, no bleeding episode occurred during anticoagulation therapy. This case supported early initiation of anticoagulation in such patients.

Successful treatment of repeated hematemesis secondary to postsclerotherapy esophageal ulcer in a cirrhotic patient: A case report.

Esophageal variceal bleeding is a common lethal complication of cirrhosis. Endoscopic injection sclerotherapy (EIS) is one of the major endoscopic approaches for treating esophageal variceal bleeding. However, complications may occur after EIS, which mainly include retrosternal discomfort/pain, dysphagia, re-bleeding, esophageal ulcer, esophageal strictures, and esophageal perforation, etc. In this article, we reported a 36-year-old male who developed esophageal ulcer related bleeding after EIS. Currently, there is no consensus on the treatment strategy for esophageal ulcer-related bleeding after EIS. In the present case, the following treatment strategy may be effective for ulcer related bleeding. The first step is to inhibit gastric acid secretion and reduce portal pressure by intravenous infusion of esomeprazole and somatostatin, respectively. The second is local hemostasis by oral norepinephrine and lyophilizing thrombin powder. The third is to protect digestive tract mucosa by oral Kangfuxin Ye and aluminum phosphate.

A systematic review and meta-analysis of treatment for hepatorenal syndrome with traditional Chinese medicine.

BACKGROUND: Hepatorenal syndrome (HRS) is a life-threatening complication of end-stage liver diseases. It has been reported that traditional Chinese medicine (TCM) may improve liver function, delay disease progression, alleviate symptoms, and improve quality of life in HRS patients. The study aims to systematically review the efficacy of TCM for the treatment of HRS. METHODS: Publications were searched electronically from China National Knowledge Infrastructure (CNKI), Wanfang, VIP, PubMed, and EMBASE databases. Odds ratio (OR) and standardized mean difference (SMD) with 95% confidence interval (CI) were calculated. Heterogeneity was assessed. The Cochrane Collaboration's tool was used to assess the risk of bias. RESULTS: Fourteen randomized controlled trials involving 788 patients with HRS were included. Random generation sequence was reported in only two studies. Blinding was not used in any study. Compared to conventional treatment without TCM, TCM led to a significant survival benefit during hospitalization (OR: 0.18; 95% CI: 0.08-0.39; P<0.0001), a significantly higher complete response (OR: 3.20; 95% CI: 2.06-4.97; P<0.00001), and a significantly lower no response (OR: 0.20; 95% CI: 0.14-0.30; P<0.00001). Partial response was not significantly different between the two groups (OR: 1.39; 95% CI: 0.90-2.15; P=0.14). Regardless of TCM, blood urea nitrogen and abdominal circumference were significantly decreased, and urine volume was significantly increased after treatment. Compared to conventional treatment without TCM, TCM led to a significantly lower serum creatinine, blood urea nitrogen, bilirubin, plasma ammonia, and abdominal circumference and significantly higher urine volume after treatment. There was significant heterogeneity. CONCLUSIONS: TCM might have a better survival and a higher complete response in patients with HRS. However, the quality of published studies was unsatisfactory.

Xuebijing Injection Combined with Antibiotics for the Treatment of Spontaneous Bacterial Peritonitis in Liver Cirrhosis: A Meta-Analysis.

BACKGROUND AND AIM: Spontaneous bacterial peritonitis (SBP) is one of the most common complications of liver cirrhosis. Antibiotics are the main treatment regimen of SBP. Traditional Chinese medicine Xuebijing injection has been used in such patients. Our study aimed to overview the efficacy of Xuebijing injection combined with antibiotics for the treatment of SBP. METHOD: We searched the PubMed, Embase, China National Knowledge Infrastructure, VIP, and Wanfang databases. The search items included "Xuebijing", "peritonitis", "liver cirrhosis", and "random" to identify all relevant randomized controlled trials (RCTs). The Cochrane risk of bias tool was used to assess the study quality. The odd ratios (ORs) with 95% confidence intervals (CIs) were calculated by using a random-effect model. Heterogeneity was also calculated. RESULTS: A total of 9 RCTs were included. The study quality was unsatisfied. The overall (OR = 2.95, 95% CI = 1.97-4.42, p < 0.00001) and complete (OR = 2.18, 95% CI = 1.57-3.04, p < 0.00001) responses were significantly higher in the Xuebijing injection combined with antibiotics group than the antibiotics alone group. The incidence of cirrhosis related complications, including hepatic encephalopathy and hepatorenal syndrome, was lower in the Xuebijing injection combined with antibiotics group than the antibiotics alone group. No significant heterogeneity was observed among studies. CONCLUSION: Additional use of Xuebijing injection may improve the efficacy of antibiotics for the treatment of SBP in liver cirrhosis. However, due to a low level of current evidence, we did not establish any recommendation regarding the use of Xuebijing injection for the treatment of SBP.

Clinical characteristics and outcomes of traditional Chinese medicine-induced liver injury: a systematic review.

BACKGROUNDS: Traditional Chinese medicine (TCM) is becoming increasingly popular and related adverse events are often ignored or underestimated. AIMS: This systematic review aimed to evaluate the clinical characteristics and outcomes of TCM-induced liver injury (TCM-ILI) and to estimate the proportion of TCM-ILI in all drug-induced liver injuries (DILI). METHODS: China National Knowledge Infrastructure, Wanfang, VIP, PubMed, and Embase databases were searched. Demographic, clinical, and survival data were extracted and pooled. Factors associated with worse outcomes were calculated. For the proportion meta-analyses, the data were pooled by using a random-effects model. RESULTS: Overall, 21,027 articles were retrieved, of which 625 were finally included. There was a predominance of female and older patients. The proportion of liver transplantation was 2.18% (7/321). The mortality was 4.67% (15/321). Male, higher aspartate aminotransferase and direct bilirubin, and lower albumin were significantly associated with an increased risk of death/liver transplantation in TCM-ILI patients. The proportion of TCM-ILI in all DILI was 25.71%. The proportion was gradually increased with year. CONCLUSIONS: Our work summarises current knowledge regarding clinical presentation, disease course, and prognosis of TCM-ILI. TCM can result in hepatotoxicity, even death or necessitate life-saving liver transplantation. Governmental regulation of TCM products should be strictly established.

Tusanqi-Related Sinusoidal Obstruction Syndrome in China: A Systematic Review of the Literatures.

In West, sinusoidal obstruction syndrome (SOS) is often complicated with hemopoietic stem cell transplantation. By comparison, in China, SOS is frequently caused by Tusanqi-containing pyrrolizidine alkaloids. A systematic review aimed to evaluate the clinical profiles, diagnostic workup, treatment, and outcomes of Tusanqi-related SOS in China. All relevant articles were searched via PubMed, China Knowledge Resource Integrated, VIP, and Wanfang databases. Case reports were defined, as the data were available in every individual patient. Otherwise, case series were defined. Overall, 106 articles were eligible. Fifty-six case reports included 84 individual patients with SOS secondary to Tusanqi alone. All of them presented with ascites, but only 1 patient presented with upper gastrointestinal bleeding. The 1-, 3-, and 6-month cumulative survival rate was 98%, 87%, and 76%, respectively. Increased bilirubin and aspartate transaminase levels were significantly associated with poor outcome. Thirty-one case series included 402 patients with SOS secondary to Tusanqi alone. Ascites was observed in 94% of patients, but upper gastrointestinal bleeding was observed in 40% of patients. Recovery, stabilization, progression, and death were observed in 41%, 30%, 14%, and 16% of patients, respectively. Nineteen case series included 281 patients with SOS secondary to mixed etiologies. The pooled proportion of Tusanqi-related SOS was 66% (95% confidence interval: 56%-75%). Tusanqi is a major cause of SOS in China. Ascites is the most common clinical presentation of Tusanqi-related SOS. Despite a relatively good short-term outcome, further studies should be necessary to explore the long-term outcome and refine the treatment strategy.
